20090116529 | SEMICONDUCTOR LASER APPARATUS, METHOD OF MANUFACTURING SEMICONDUCTOR LASER APPARATUS, AND OPTICAL PICKUP APPARATUS - A monolithic red/infrared semiconductor laser device is joined to a blue-violet semiconductor laser device. The distance between a blue-violet emission point in the blue-violet semiconductor laser device and an infrared emission point in an infrared semiconductor laser device is significantly shorter than the distance between a red emission point in a red semiconductor laser device and the infrared emission point. A blue-violet laser beam, a red laser beam, and an infrared laser beam respectively emitted from the blue-violet emission point, the red emission point, and the infrared emission point are introduced into a photodetector after being incident on an optical disk by an optical system comprising a polarizing beam splitter, a collimator lens, a beam expander, a λ/4 plate, an objective lens, a cylindrical lens, and an optical axis correction element. | 05-07-2009 |
20100080106 | OPTICAL PICKUP APPARATUS AND OPTICAL DISC APPARATUS - An optical pickup apparatus changes a propagation direction of luminous fluxes, out of a laser light reflected by a disc, in four luminous flux regions set about a laser optical axis so as to mutually disperse these luminous fluxes. A signal light region in which only a signal light is present appears on a detection surface of a photodetector. A plurality of sensors for a signal light are placed at positions irradiated with the signal light within the region. When an arithmetic process is performed on a detection signal outputted from each sensor, a DC component occurring in a tracking error signal is suppressed. | 04-01-2010 |

20110193616 | SEMICONDUCTOR INTEGRATED CIRCUIT AND DATA PROCESSING SYSTEM - An arrangement for detecting local light irradiation in an illegal attack attempt to intentionally induce a malfunction or faulty condition is formed on a small chip occupancy area so as to provide high detection sensitivity. In a region containing a logic circuit, a plurality of series-coupled detection inverters are distributively disposed as photodetector elements having a constant logical value of primary-stage input. When at least one of the series-coupled detection inverters is irradiated with light, an output thereof is inverted, thereby producing a final output through the series-coupled detection inverters. Based on the final output thus produced, local light irradiation can be detected. | 08-11-2011 |

20130087943 | PREFORM NECK CRYSTALLIZATION METHOD - A neck crystallization method includes inserting a core into the neck, heating the neck using a heater group disposed along a transfer direction while rotating the preform on its axis, and transferring the preform along the transfer direction in a state in which the core is inserted into the neck, and cooling the neck of the preform in a state in which the core is inserted into the neck. The heating of the neck includes a first step that drives first heaters positioned on the upstream side in the transfer direction at a first power, and a second step that drives second heaters positioned on the downstream side of the first heaters at a second power that is lower than the first power until the temperature of the neck reaches a crystallization temperature zone. | 04-11-2013 |
20130087954 | METHOD FOR PRODUCTION OF HEAT-RESISTANT CONTAINER - An invention of a method for production of a heat-resistant container, in which a raised bottom portion is displaced inwardly by reduction in internal pressure, is disclosed. The method is characterized by forming a raised bottom portion | 04-11-2013 |
20130175738 | NECK CRYSTALLIZATION SYSTEM - The neck crystallization system includes a rectangular stage, a plurality of sprockets that are disposed on the stage, and an endless member that is fitted around the plurality of sprockets. A transfer path that is formed in an area in which the endless member is disposed, includes first to fourth linear transfer paths. A plurality of heating sections provided along at least the first to third linear transfer paths, a cooling section disposed along at least the fourth linear transfer path, a molded article supply section that supplies the molded article at a position on the upstream side of the plurality of heating sections, and a molded article removal section that removes the molded article at a position between the cooling section and the molded article supply section, are provided along the transfer path in which a plurality of transfer members that respectively support the molded article are transferred. | 07-11-2013 |
